Step 2: Put Together

Step 1: Parts

First you need small wire (shown in first picture) then take out about 2.5 inches of wire and then wind the silver wire around the plastic insulation for the wire then you need a penny and some super glue

I stumbled upon this by mistake when make igniters for my model rockets and I just used a regular wire and a 9 volt so thanks for the advice I think I might solder the wire to the penny and then tape another penny in top of it

Ok so what causes the heating? I mean if you hook this up to a battery or some wall wart or something you need to add that or this is just a non-instructable. Not trying to be mean but this seems unfinished. Also if this heats up and you are using super glue you are going to heat the cyanocryalate glue releasing cyanide, while the small amount here probably won't do any lasting harm, repeated exposure will! Please elaborate on this and include what type of wire. I suggest nichrome and some sort of heat resistant bonding agent and a regulated power supply.
